* Nominal tons are at AHRI/ISO 13256-1 GLHP conditions. Two-stage units may be operated in single-stage mode if desired, where smaller
capacity is required. For example, a model 026 may be used as a 1-1/2 ton unit if “locked” into 1st stage operation only. If PSC fan is
used, unit must be “locked” into either 1st or 2nd stage. An ECM fan is required for two-stage operation and for AHRI ratings. Size air
handler for “Full Load” if operating in two-stage mode.
**When selecting an air handler based upon the above conditions, choose entering WB temperature of 67ºF. Use evaporator temperature,
CFM and capacity requirements as listed above. The air handler capacity must be at least at the minimum capacity shown in the table in
order for the AHRI rating condition to be valid. See Figure 1 for an example selection.
Note: Due to limitations in combining a geothermal split unit with a Bryant Evolution fan coil, furnace and In
Ä
nity
control, or a Bryant Evolution fan coil, furnace and Evolution controller, refer to Service Bulletins SMB 10-0007 and
DSB 10-0007.
